10. Select all of the BBXs and all of the MCCs, and use the full
optimization function. The full optimization function performs TX
calibration, BLO download, TX audit, all TX tests, and all RX tests
for all selected devices.
11. If the TX calibration fails, repeat the full optimization for any failed
paths.
12. If the TX calibration fails again, correct the problem that caused the
failure and repeat the full optimization for the failed path.
13. If the TX calibration and audit portion of the full optimization passes
for a path but some of the TX or RX tests fail, correct the problem
that caused the failure and run the individual tests as required until
all TX and RX tests have passed for all paths.
Site Types
Sites are configured as Omni/Omni or Sector/Sector (TX/RX). Each type
has unique characteristics and must be optimized accordingly.
NOTE
For more information on the differences in site types, please
refer to the applicable BTS/Modem Frame Hardware Installation
and Functional Hardware Description manuals.
Cell-Site Data File
The Cell-Site Data File (CDF) contains information that defines the
BTS and data used to download files to the devices. A CDF file must be
placed in the applicable BTS folder before the LMF can be used to log
into that BTS. CDF files are normally obtained from the CBSC using a
floppy disk. A file transfer protocol (ftp) method can be used if the LMF
computer has that capability.
The CDF includes the following information:
Download instructions and protocol
Site specific equipage information
C-CCP shelf allocation plan
- BBX equipage (based on cell-site type) including redundancy
- CSM equipage including redundancy
- MCC (MCC24E, MCC8E, or MCC-1X) channel element allocation
plan. This plan indicates how the C-CCP shelf is configured, and
how the paging, synchronization, traffic, and access channel
elements (and associated gain values) are assigned among the (up to
12) MCCs in the shelf.
CSM equipage including redundancy
Effective Rated Power (ERP) table for all TX channels to antennas
respectively. Motorola System Engineering specifies the ERP of a
transmit antenna based on site geography, antenna placement, and
government regulations. Working from this ERP requirement, the
antenna gain, (dependent on the units of measurement specified) and
antenna feed line loss can be combined to determine the required
power at the top of the BTS frame. The corresponding BBX output
level required to achieve that power level on any channel/sector can
also be determined.
